Download or read book American and Australasian Marsupials written by Nilton C. Cáceres and published by Springer Nature. This book was released on 2023-06-30 with total page 1648 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the evolution, biogeography, systematics, taxonomy, and ecology of New World and Australasian marsupials, greatly expanding the current knowledge base. There are roughly 140 species of New World marsupials, of which the opossum is the best known. Thanks to recent research, there is now an increasing amount of understanding about their evolution, biogeography, systematics, ecology, and conservation in the Americas, especially in South America. There are also some 270 marsupial species in the Australasian region, many of which have been subject to research only in recent years. Based on this information and the authors’ extensive research, this book provides comprehensive insights into the world's marsupials. It will appeal to academics and specialized researchers, students of zoology, paleontology, evolutionary biology, ecology, physiology and conservation as well as interested non-experts.

Available in PDF, EPUB and Kindle. Book excerpt: We hear routinely about dinosaurs unearthed in the Gobi Desert, about new marsupials found in the forests of Madagascar, about darling deep sea squid in the polar regions. These discoveries tend to be accompanied by wondrous feats of adventuring scientists. But just as one can experience the world in a backyard, or farther reaches of the world with a good book and a comfy armchair, scientists themselves know that the natural history museums of the world contain some of the best terrain for discovering new species. In recent years scientists have found in museum drawers and cabinets a new rove beetle collected by Darwin, a tiny lungless salamander thinner than a matchstick, a monkey from the Brazilian rainforest, and a 40 million year old beardog. The Lost Species shares the thrill of spelunking in museum basements, digging in museum trays, and breathing new life in taxidermied beings--a in a days' adventure for the scientists in this book. These discoveries help tell the story of life, and the priceless collections of natural history museums.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: We describe a new species of the didelphid marsupial genus Monodelphis from Brazil, where it appears to be widely distributed in the states of Pará, Mato Grosso, Rondônia, and Acre. Monodelphis saci, new species, belongs to the subgenus Mygalodelphys, and analyses of DNA sequence data suggest that it is most closely related to M. handleyi, M. osgoodi, and M. peruviana. Diagnostic morphological traits include pelage coloration, qualitative aspects of craniodental morphology, and a distinctive range of morphometric variation. The new species has sometimes been misidentified in the literature as M. kunsi, a distinct but apparently allopatric taxon. Monodelphis saci occurs sympatrically with M. emiliae, M. glirina, and M. touan in the rainforested lowlands south of the Amazon River.

Download or read book Walker's Mammals of the World written by Ronald M. Nowak and published by JHU Press. This book was released on 2018-06-15 with total page 785 pages. Available in PDF, EPUB and Kindle. Book excerpt: The preeminent guide to the world’s mammals is now enhanced with a dramatically expanded volume covering 19 orders, including such creatures as elephants, armadillos, and manatees. Since its first publication in 1964, Walker's Mammals of the World has become a favorite guide to the natural world for general readers and professionals alike. This new Walker's volume is a completely revised and updated compendium of information on five of the earliest clades to diverge from ancient mammal stock. Uniquely comprehensive in inimitable Walker's style, it incorporates a full account of every genus that has lived in the past 5,000 years. Every named species of each genus is listed in systematic order and accompanied by detailed descriptions of past and present range. This new edition includes • 500+ full-color images throughout • citations to more than 2,200 new references • extensive bioconservation data, with discussion of every species in an IUCN Red List threatened category This volume's thorough updates reflect 20 years of advances in our knowledge of taxonomy, ecology, behavior, life history, and conservation. Substantive changes to 100% of previously existing generic accounts, plus the addition of 17 entirely new generic accounts, double the information in the last edition on the 19 orders covered. The black-and-white illustrations of earlier editions have been replaced by over 500 superb new color images. Remaining true to Ernest P. Walker's vision, the text smoothly combines in-depth scholarship with a popular, readable style to preserve and enhance what the Washington Post called a "landmark of zoological literature."

This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new species of the didelphid marsupial genus Monodelphis is described from southeastern Brazil. The new species is closely related to Monodelphis kunsi Pine, 1975, and other members of the M. adusta group, but differs from those species and from other congeneric taxa by unique external and cranial characters and by cytochrome-b and nuclear DNA sequences. Diagnostic morphological characters of the new species include uniformly brownish dorsolateral pelage without distinct stripes or other sharp pigment discontinuities; diminutive eyes and ears; a remarkably long and narrow rostrum; apparent loss of an interparietal ossification; and the presence of diastemata between C1 and P1, P1 and P2, c1 and p1, p1 and p2, and p2 and p3. The new species is known from the Atlantic Forest (Mata Atlântica) of southeastern Brazil, where it occurs sympatrically with four other congeners (M. americana, M. iheringi, M. scalops, M. dimidiata) and seems to be restricted to montane habitats.

Download or read book A New Species of Marmosops (Marsupialia, Didelphidae) from the Pakaraima Highlands of Guyana, with Remarks on the Origin of the Endemic Pantepui Mammal Fauna written by Robert S. Voss and published by . This book was released on 2013 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new species of the didelphid marsupial genus Marmosops is described from the Pakaraima Highlands of western Guyana and from two highland sites in eastern Venezuela. All known specimens were collected on sandstone table mountains (eroded fragments of the Roraima Formation) in the eastern subregion of Pantepui. The new species, M. pakaraimae, is one of only seven mammals known to be endemic to Pantepui, and phylogenetic analyses of cytochrome-b sequence data indicate that its sister taxon is M. parvidens, a geographically adjacent lowland species. Our results, together with those from phylogenetic studies of other Pantepui endemic mammals, suggest that at least some of these highland taxa evolved from lowland species in the late Cenozoic and are neither ancient relicts of tepui vicariance nor the descendents of long-distance-dispersing Andean progenitors.

Available in PDF, EPUB and Kindle. Book excerpt: From the Foreword Umberto Quattrocchi has brought us some amazing and useful works through the various dictionaries that he has compiled. This time it is for two very important plant families the palms and the cycads that are synthesized here in these two volumes. Each entry is fascinating not just for the botany and full nomenclature of the plant species but for all the associated uses, folklore and interactions with other organisms. ...These entries are fascinating glimpses of natural history. ... Botanists, conservationists, ethnobotanists, anthropologists, geographers, bird watchers, naturalists, historians and those of many other disciplines will find these volumes a most valuable and useful resource. It is the sort of book that will be in frequent use in my library. ----- Professor Sir Ghillean Prance FRS, VMH, Former Director, Royal Botanic Gardens, Kew Following the same format as Umberto Quattrocchi’s highly praised and well-used previous works, The CRC World Dictionary of Palms: Common Names, Scientific Names, Eponyms, Synonyms, and Etymology brings together the vast and scattered literature on palms and cycads to provide better access to information on these economically important plants. Each genus and species has a detailed morphological description and includes a list of synonyms and vernacular names in many languages. Bibliographies accompany each entry which are comprehensive, up-to-date and multi-lingual. The detailed information for every entry on habitats, economic uses, historical and biographical data, botanical exploration, and linguistics will be useful for any library involved with botany, herbal medicine, pharmacognosy, medicinal and natural product chemistry, ecology, ethnobotany, systematics, general plant science, agriculture or horticulture. Umberto Quattrocchi is the author of the bestselling CRC World Dictionary of Plant Names, winner of the prestigious Hanbury Botanical Garden Award. His most recent multi-volume work, CRC World Dictionary of Medicinal and Poisonous Plants, received strong praise as being "... an unparalleled starting place—a tool of first resort for any thoughtful researcher. Quattrocchi and CRC have delivered a dictionary like no other, a learned finger pointing in the right direction." —John de la Parra, Northeastern University, Boston, Massachusetts, USA, from Economic Botany, Vol. 68, 2014

Available in PDF, EPUB and Kindle. Book excerpt: In this report, the first installment of a comprehensive revision of the didelphid marsupial genus Marmosops, we revise the species of the subgenus Sciophanes. Based on morphological character variation among almost 300 examined specimens--which we interpret in the context of a previously published analysis of molecular sequence data--this revision recognizes 12 valid species in three monophyletic species groups: the Parvidens Group (including M. pakaraimae, M. parvidens, and M. pinheiroi), the Fuscatus Group (M. carri, M. fuscatus, M. handleyi, and M. invictus), and the Bishopi Group (M. bishopi, M. juninensis, M. ojastii, and two new species). For each species we summarize information about type material, ecogeographic distribution, and diagnostic morphological characters. Despite our diligent search for relevant material in North and South American museums, the absence of any specimens of Sciophanes from vast Amazonian and Andean landscapes with seemingly suitable habitat suggests that significant range extensions and/or new species will result from future inventory fieldwork.

Download or read book Predators with Pouches written by Menna Jones and published by CSIRO PUBLISHING. This book was released on 2003-04-30 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predators with Pouches provides a unique synthesis of current knowledge of the world’s carnivorous marsupials—from Patagonia to New Guinea and North America to Tasmania. Written by 63 experts in each field, the book covers a comprehensive range of disciplines including evolution and systematics, reproductive biology, physiology, ecology, behaviour and conservation. Predators with Pouches reveals the relationships between the American didelphids and the Australian dasyurids, and explores the role of the marsupial fauna in the mammal community. It introduces the geologically oldest marsupials, from the Americas, and examines the fall from former diversity of the larger marsupial carnivores and their convergent evolution with placental forms. The book covers all aspects of carnivorous marsupials, including interesting features of life history, their unique reproduction, the physiological basis for early senescence in semelparous dasyurids, sex ratio variation and juvenile dispersal. It looks at gradients in nutrition—from omnivory to insectivory to carnivory—as well as distributional ecology, social structure and conservation dilemmas.

Download or read book Phylogenetic Studies on Didelphid Marsupials written by Robert S. Voss and published by . This book was released on 2003 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to test the results of a previous study of didelphid marsupial phylogeny based on IRBP nuclear gene sequences (Jansa and Voss, 2000. Phylogenetic studies on didelphid marsupials I. Introduction and preliminary results from nuclear IRBP gene sequences. Journal of Mammalian Evolution 7: 43-77), we surveyed external, cranial, dental, and karyotypic characters among a more densely taxon-sampled didelphine ingroup. Separate maximum-parsimony analyses of these nonmolecular data and of a new (taxon-dense) IRBP matrix yielded superficially dissimilar strict-consensus topologies. However, no didelphine clade that was even moderately well supported by either separate analysis was contradicted by any equivalently well-supported clade in the other. Instead, all examples of taxonomic incongruence involved weak nodal support from one or both datasets. A maximum-likelihood analysis of the IRBP data produced a consensus topology that was completely congruent with, although slightly more resolved than, the maximum-parsimony consensus. A combined (simultaneous) maximum-parsimony analysis of both datasets (nonmolecular + IRBP) produced a consensus topology that closely resembled the results of analyzing IRBP separately. Most of the didelphine relationships previously reported by Jansa and Voss (op. cit.) are supported by these analytic exercises, with some notable exceptions. The taxon currently known as Marmosa canescens is conspicuously divergent from congeneric species and variously clusters with three different groups ("other Marmosa" + Micoureus, Monodelphis, or higher didelphines (= clade H of Jansa and Voss, op. cit.)) in several parsimony-equivalent resolutions of a fourfold basal polytomy in the IRBP and combined-data consensus topologies. Even without canescens, however, the genus Marmosa is not demonstrably monophyletic. The nomenclatural consequences of these results are discussed, and a new genus is described for "Marmosa" canescens. Future analyses should test the monophyly of other speciose didelphine genera, but new sources of character data will be needed to offset the loss of resolution and decreased nodal support that are often caused by denser taxon sampling.

Download or read book A Revision of Philander (Marsupialia, Didelphidae). written by Robert S. Voss and published by . This book was released on 2018 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first installment of a revision of the didelphid marsupial genus Philander, commonly known as gray four-eyed opossums. Although abundant and widespread in lowland tropical forests from southern Mexico to northern Argentina, species of Philander are not well understood taxonomically, and the current literature includes many examples of conflicting species definitions and nomenclatural usage. Our revision is based on coalescent analyses of mitochondrial gene sequences, phylogenetic analyses of mitochondrial and nuclear genes, morphometric analyses, and firsthand examination of relevant type material. Based on these results, we provisionally recognize eight species, of which three are formally treated in this report: P. quica (Temminck, 1824), an Atlantic Forest endemic formerly known as P. frenatus (Olfers, 1818); P. canus (Osgood, 1913), a widespread species formerly treated as a synonym or subspecies of P. opossum (Linnaeus, 1758); and P. pebas, a new species endemic to Amazonia. The remaining, possibly valid, species of Philander can be allocated to two clades. The first is a cis-Andean complex that includes P. andersoni (Osgood, 1913); P. mcilhennyi Gardner and Patton, 1972; and P. opossum. The second is a trans-Andean complex that includes P. melanurus (Thomas, 1899) and P. pallidus (Allen, 1901). Among other nomenclatural acts, we designate a neotype for the long-problematic nominal taxon Didelphis superciliaris Olfers, 1818, and (in an appendix coauthored by Renate Angermann), we establish that Olfers' coeval binomen D. frenata is based on an eastern Amazonian type and is a junior synonym of P. opossum.
